IMPROVEMENT IN HARVES'IER-PITMEN.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it may concem:

Be it known that I, CHARLES E -ROPER, of Canton, in the county of Stark,and in the State of Ohio,

have invented certain new and useful Improvements in Pitmen; and dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon.

The nature of my invention consists in the construction and generalarrangement of a pitman, for reapers and mowers, and other machinesrequiring motion either in or out of a direct line;

In order to enable othersskilledin the art to which my inventionappertains, to make and'use the same, I will now proceed to describe itsconstruction and operation,'referring to the annexeddrawings, which forma part of this specification, and in which Figure 1 is aperspectiveview; A

Figure 2 is avertical of the joint; and

Figure 3, a side view of the tapeiing bolt;

. A represents the end of the knife of a reaper and mower, on which aretwo lugs, or ears, B B. Between the two cars B B, the ball 0 of aball-and socket joint is placed, and to obtain the rigidity necessary toa perfect working of said joint, the ball 0 is secured by means of ataper-bolt, D, said bolt passing through the two ears, or lugs, and theball.

All wear and tear, of the joint are easily overcome, by simplyturningthe said taper-bolt D to any desired degree of tightness.

The ball 0 is enclosed in a box, E, composed 01 two pieces formed tofit, or cover the ball, said pieces, or box being confined to theirplaces by a strap, F, passing around the box; and said box E iscontrolled by an adjusting-screw, G, one end of which is contained in ahollow tube, H, to which the strap F is secured.

The other end of the screw G is made concave, to

-low tube H, and the other in a similar tube, H.

, The hollow tube H has a similar arrangement of adjusting=screw,jam-nut, strap, and box, as described A for the tube H, and markedrespectively on the drawing as G, I, F, and E.

The adjusting-centre J is controlled by the adjusting-screws G G,working, in connection with ball-andsocket joint, at both ends ofpitman, and by the jamnuts K K, as shown in fig. 1.

By this means, I obtain a pitman whichis adjustable and accommodating toany or all depressions in surface, being oapable of extension orcontraction, and being made entirely of gas-pipe and malleable iron, orits equivalent, can be made lighter and at less expense than those nowin use.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

The combination of box E, strap F, tube H, pipe J
